vintage restaurant ware ironstone china platter, pines & mountains airbrush pattern

Vintage white ironstone china platter or oval plate with 'mountains are calling' sort of a scene, airbrush pattern in grey and green. This is Jackson china, American made.

This is 12 1/2" long, heavy china made for restaurant (or railroad dining car?) use. It's noticeably worn from age and use, though has no chips or cracks.
